Doped Carbon Nanotubes Close the Gap with Copper's Conductivity

Carbon nanotubes have long promised superior electrical properties and lighter weight than copper, but achieving stable, high-conductivity variants has remained elusive. A new approach using chemical dopants to enhance electron flow brings this possibility significantly closer, potentially revolutionizing applications from power transmission to electronics. This breakthrough points toward solving the practical challenges that have delayed nanotube-based wiring for years.
